hi there
I was infected with a trojan virus a few weeks ago and it slowed down my comp and got various pop ups telling me that i had a malware and had to buy an antivirus software...then all of a sudden the pop ups etc disappeared and i have no real major problems with it apart from java constantly popping up telling me that my limewire files are not supported (i deleted limewire because i thought the trojan was from a download i made, i downloaded limewire again to see if these pop ups would stop but the didnt). Anyways,,today i went to my laptop and it took nearly 30min to load and then i kept on getting a mcafee alert telling me that my comp was infected with a trojan they couldnt remove. Every time i went to open internet explorer, this alert would appear and close the web page before it had even loaded. Im desperate to fix it and i cant part with it for long as i do all my work on it! is there anyway i can fix it myself? McAfee have done load of scans but cant get rid of it, spybot search and destroy can also detect it but cant help the problem..i am at my wits end! please someone help!

P.S: A friend of mine had a trojan before and found a process of getting rid of it on this site but has since lost what she printed out. If anyone knows what i am talking about, please get back to me asap. i dont think i can handle another day of no internet!

Thanks!

Since you cannot use your Internet, you are going to need access to another computer (family member, friend, etc) with an Internet connection.

Please download the following programs and save to a USB stick or CD:
Sysclean Package. Be sure to print out the "How to use Sysclean Package Instructions".
Virus Pattern Files - (Pattern files are usually named lptxxx.zip, where xxx is the pattern file number)
SUPERAntiSpyware Free
SUPERAntiSpyware Free Definition files - (Be sure to download both the Core and Trace Definitions)
ATF Cleaner
Dr.Web CureIt
WinSockFix.
Be sure to print out and save the instructions provided in the Winsock Repair Tutorial in case we need to use this tool.
HijackThis Installer. This is HijackThis 2.0.2 but it is an automatic setup version which will install HJT in the proper location if we need to use it. DO NOT fix anything with HijackThis unless advised.

Transfer all these programs directly to the Desktop of the infected computer <- (Important!)

For the Sysclean Package do this:
  • Create a new folder on drive "C:\" and rename it Sysclean - (C:\Sysclean).
  • Place the sysclean.com inside that folder.
  • Extract (unzip) the lptxxx.zip pattern file into the Sysclean folder where you put sysclean.com. DO NOT scan yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup [but before the Windows icon appears] press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Note: Some anti-virus programs such as Avast will alert you to a virus attack when running sysclean so it's best to disable them before going to the next step.

Scan with Sysclean as follows:
  • Open the Sysclean folder and double-click on sysclean.com to start the scanning process.
  • Put a check mark on the "Automatically clean or delete infected files" option by clicking in the checkbox.
  • Click the Advanced >> button.
  • The scan options appear. Select the "Scan all local fixed drives".
  • Click the "Scan button" on the Trend Micro System Cleaner console.
  • It will take some time to complete. Be patient and let it clean whatever it finds.
  • Another MS-DOS window appears containing the log file (sysclean.log) generated in the same folder where the scan is completed - C:\Sysclean.
  • To view the log, click the "View button" on the Trend Micro System Cleaner console. The Trend Micro Sysclean Package - Log window appears.
    • The Files Detected section shows the viruses that were detected by System Cleaner.
    • The Files Clean section shows the viruses that were cleaned.
    • The Clean Fail section shows the viruses that were not cleaned.
  • Exit when done.
When using Sysclean its best to use the Administrator's account or an account with Administrative rights otherwise you will not have access rights to scan some locations. You can also Use the "Run As" Command to Start a Program as an Administrator. Even when doing that, the scanning process may result in "Access Denied" messages for some files. This is normal because these files are protected by the system.

Scan with Dr.Web CureIt as follows:
  • Double-click on cureit.exe to start the program. (ignore any prompts to update or check for a new version)
  • When the Dr.Web opens, an "Express Scan of your PC" notice will appear.
  • Under "Start the Express Scan Now", Click "OK" to start. This is a short scan that will scan the files currently running in memory and when something is found, click the Yes button when it asks you if you want to cure it.
  • Once the short scan has finished, Click Options > Change settings
  • Choose the "Scan tab" and UNcheck "Heuristic analysis"
  • Back at the main window, click "Select drives" (a red dot will show which drives have been chosen)
  • Then click the "Start/Stop Scanning" button (green arrow on the right) and the scan will start.
  • When done, a message will be displayed at the bottom advising if any viruses were found.
  • Click "Yes to all" if it asks if you want to cure/move the file.
  • When the scan has finished, look if you can the next icon next to the files found. If so, click it, then click the next icon right below and select "Move incurable".
    (This will move it to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if it can't be cured)
  • Next, in the Dr.Web CureIt menu on top, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop. (You can use Notepad to open the DrWeb.cvs report)
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
Remember to re-enable your anti-virus program when done.

Now double-click SUPERAntiSypware.exe and use the default settings for installation.
  • Navigate to the SUPERAntiSpyware folder in C:\Program Files and unzip both the Core and Trace defintion files.
  • An icon will have been created on your desktop. Double-click that icon to launch the program.
  • Under the "Configuration and Preferences", click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the Scanning Control tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method.

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
  • Click Close to exit the program.
